Steering Systems Face Change: Electric and Hydraulic Compared in Transitional Times
Shift in Auto Mechanic Training: Embracing Electric Power Steering
The world of auto mechanics is undergoing a significant transformation, with the focus shifting from traditional hydraulic power steering (HPS) to modern electric power steering (EPS). This transition is profoundly impacting mechanic training and curriculum, requiring a greater emphasis on electrical and electronic systems, software diagnostics, and control systems.
Expanded Curriculum Scope
Training programs now emphasize understanding electric motors, microcontrollers, sensors, and software that control the EPS system, instead of primarily hydraulic pumps, hoses, and fluid maintenance. ATC Surrey's auto mechanic training program, for instance, provides hands-on experience with a wide range of systems, preparing students to work confidently in any automotive repair environment.
Diagnostic Skills
Mechanics need to learn to use specialized electronic diagnostic tools and software to troubleshoot EPS issues, including sensor faults and electronic control unit (ECU) communications, which are absent in traditional hydraulic systems.
Safety and Functional Standards
EPS is a safety-critical application with stringent automotive standards, requiring training on safety protocols and system redundancy concepts. As EPS facilitates by-wire steering and variable assist features tailored by software, training includes modules on how EPS interfaces with autonomous vehicle systems and how to service these advanced technologies.
Reduced Mechanical Complexity, Increased Electronic Complexity
While EPS reduces mechanical parts like pumps and fluid lines—simplifying some physical maintenance—mechanics must gain expertise in electronics, firmware updates, and recalibration techniques.
The Rise of Electric and Hybrid Vehicles
The industry trend points towards wider adoption of EPS, especially with the rise of electric and hybrid vehicles. In many modern vehicles, EPS is the exclusive steering system due to its precision and adaptability.
Hydraulic Systems: Still in Use
Hydraulic systems aren't going away completely; many heavy-duty vehicles and trucks continue to use them for their durability and performance in demanding conditions. Hydraulic systems are known for their smooth, natural steering feel but come with drawbacks like fluid leaks, worn hoses, and pump failures.
Mastery of Both Systems
Mastering both hydraulic and electric steering systems will set a technician apart as capable and adaptable. Understanding the differences between Hydraulic and Electric Power Steering is essential for success in auto mechanic training programs. Training covers fluid inspection and replacement for hydraulic systems, electrical diagnostics for EPS components, steering angle sensor calibration, and safety protocols for handling electronic systems.
Advantages of EPS
EPS offers advantages such as reduced weight, lower maintenance requirements, and improved fuel efficiency. For instance, EPS eliminates hydraulic fluid and pumps, using an electric motor to provide steering assistance based on driver input.
In summary, automotive mechanic education is evolving from a hydraulic/mechanical-centric curriculum towards a hybrid of mechanical and advanced electronics training, emphasizing software, embedded systems, and electronics diagnostics to proficiently service modern EPS-equipped vehicles.
